Windows 10: CTRL+SHIFT keyboard combos not working

I've been using Windows 10 at home for a couple years. I use numerous keyboard combinations that involve CTRL+SHIFT. For example: CTRL+SHIFT+V to paste text without formattingCTRL+SHIFT+T to reopen a closed tab in Google ChromeCTRL+SHIFT+E to export photos in Adobe Lightroom And so on.My problem is that all CTRL+SHIFT keyboard combos stopped working. I don't know how or why! Suddenly one day they didn't work any more. Whenever I press CTRL and SHIFT at the same time, I get a beep, and the desired combinations don't do anything at all. This problem persisted for more than six months. I tried ev

CTRL-SHIFT-DEL combination is locked in all the browsers.

1. Open any web browser
2. Try the CTRL-SHIFT-DEL combo to call the clear history window

Result: the combo doesn't work in any browser.

It seems this combo was broken due to the latest WIndows updates. Does anyone know how to fix this?

Adding and removing keyboard language shouldn't interfere with anything. If you don't use any other language, you should only have singled kb layout.

Also running

in command prompt

would be wise, to check system files are all there, and fine

 

keyboard hotkeys with ctrl partially working

The shoth answer is NO
Test results with two languages: English and Hebrew; leftAlt+shift set as sequential switch
I can set English to any ctrl+<num> and it will always switch correctly from Hebrew to English (and disable chrome tab switch for that <num>

No ctrl+<num> or ctrl+shift+<num> or (with disabled sequential) leftAlt+shift+<num> allows to switch to Hebrew. The only mean available to me to have Hebrew is the leftAlt+shift sequential shift

The long answer is that Surprisingly, yesterday I could switch *once* to Hebrew with ctrl+<a num which I don't remember>
